10' sub box for behind double cab driver side seat

I'm parting ways with my stereo stuff and was hoping someone would like to purchase a homemade sub box that I had in my 2013 dbl cab 4x4. It is a sealed box that holds a 10 inch sub and is prewired. I'm not sure how much it is worth as it works great but I did a crap job on the carpet on the outside. It measures roughly 17' wide, 7' deep at bottom, 3.5' deep at top and 19' tall
